Breakdown
PA Post Cross is a play-action pass out of Shotgun Wing Tight Flip that sells the run fake before releasing three vertical stressers into the defense. Off the play fake, one receiver rips a deep post from the boundary while a second receiver runs an over route that crosses the field underneath the post, stretching the defense horizontally and vertically at the same time. A third route works as a deep out breaking away from the formation to occupy the sideline defender, while the back releases outside on a checkdown flat route as the outlet against pressure. This is a man beater at its core, using the crossing route to create natural rub traffic and separation against man defenders, though the double move look off play-action also punishes zone defenders who bite on the run fake. Primary read progression starts with the post for the explosive shot, works to the crossing over route as the safety valve against off coverage, and ends with the flat route to the running back if the pocket collapses or the defense drops deep.
Defensive Reads
Man coverage with no deep safety help is the biggest vulnerability, since the crossing over route creates natural separation through traffic and the post has a one on one shot at the deep safety. Cover 3 with a single high safety is exposed if that safety bites on the run fake, leaving the post route wide open in the deep middle. Watch linebacker depth at the snap: if linebackers step up hard to fill run gaps, the crossing route will have a soft window underneath for an easy completion. Zone defenses that drop their flat defender deep can be beaten by the running back's checkdown, so a defender sitting too deep in the flat zone opens up an easy completion for positive yardage. Cover 4 or Cover 2 shells with two deep safeties shut this down effectively, since the post route runs directly into help, so user a safety to rob the post and force the quarterback to check down or eat pressure. Aggressive blitz packages can be countered if the running back leaks out fast enough, so track edge rushers and be ready to user a linebacker into the flat throwing lane to bait a bad read.
Usage Tips
Use pre-snap motion or a hard count to bait linebackers into committing to the run fake before the ball is snapped, since the play-action sell depends on defenders stepping up. Identify single high shells like Cover 3 or Cover 1 before the snap, since the post route has room to work against a lone deep safety. If you see two deep safeties showing Cover 2 or Cover 4, hot route the post to a deep out or comeback to avoid throwing into the safety's zone. This play pairs well with Inside Zone or QB Zone in the same set, since the identical run action keeps linebackers honest and sets up the play-action fake on later downs. Call this on early downs like first or second and medium distance situations where defenses are more willing to sell out against the run, and mix it with Mtn Escort PA Slide to give the defense two different crossing patterns off similar shot action. Watch the flat route as your built-in answer against a hard edge blitz, since the running back releasing outside gives a quick, safe outlet.
